FOLDING PORTABLE-STOVE- FRAME.

Application filed August. 23,-

The improvements relate toportable stoves and to stoves of this character which. are to be folded oritnoeked down forpacking, carrye ing or other transportation and -may be opened upandplaced in position by unskilled persons, and without the employment of tools of any description or the necessityfor malnng or breaking permanent connections. 1 The stove is intended to be used-with gasolene or other vaporburners, but certain features of the improvements may be employed with burners of other character. The stove provided by the improvements may also be used permanently iifi'desired, or in summen camps similar uses. g I

The principal objects of the improvements I are to provide a portable or camp, stove which is simple, strong and ethcient, answers all the ordinary purposes of outdoor or other light cooking and can be opened up and placed in condition for use or folded and put in conditio for carrying by any person of ordinary intcll ence and without danger that any of the p: ts will be improperlypositioned or adjusted, and willin use provide safe, convenient and efiicient means "for all ordinary cooking operations. i H

The iinproinments are illustrated in the acv companying drawings, in which 1 is a front perspectiveview OfitPOl'lk able vapor stove in position for use,'with the id-or turned up instead. of being down in horizontal position for the support of cooking utensils or appliances;

ng to the drawings, the body or fix frame 1 consists ofa rectangular i i .etal having openings 2, 3 and 4 .ch the val ie stems of the burnor. y be operated by means of a key 601' otln suitable instrument, this liGV being connected with thc inner frame of the burners being housed within the flanges 16' 1927.

An ordmarv'pair of Vpincers or plyers, however, can. be em" ployed to engage the square ends of the burner valve stems 9, I0 and llif desired. .Onthe 12 consisting of a substantially U-shaped bar having its ends 'rotatably held in sleevesilii secured to the said member, while below the front or-topmem'be-r of the body 1 is a handle;

The construction and arrangement of these diagonal rods 15 is peculiar, and this 0011-.

legs 16, in connection with'the' relations between these partsis one of the features of the improvements which render the stove simple, 7

strong and convenient. 1 The rods 15 have cor responding rods 15" at the back'of the stovewhich engage the back, bottom member, of the body in the same manner as thatin which the rods 15 engage the front members, and

the two rods are connectedby a horizontal-sec tion 15 extending through theslee-ves 17 secured inside of the legs 16. The two rods and connecting portion are made all in one the legs, andtherefore in order to make them engage the holes 14 in the body they must be and the saidv ends permitted to snap into the flexed outwardly to a slightextent and moved upwardly until theirxinturned ends register with the holes-14, when theylmay be released l1()l.QS. hO'1I1Ll-I9 a secure-connection and one which Wlll hold against all ordinary stresses to which they may be subjected in use. when disconnectedfrom the body they. fall to the position shown in dotted lines inFigI 3. and

down against thebody of the stove (see Figl their vertical flanges fit insidethe lower edge of the said body, and the, legswhich now or1n=ione side'of the; enclosing? box aresecured together in closed position by means ofthe wedge shaped loop 20 of the strap 19 secured to the outside of one of the legs, which is engaged by the latch 21, lo tatably secured on the other leg, when it is swung around so that its outer end enters the loop and is pressed into the same so that it will be wedged between it and the leg to form a secure connection, The outer inwardly turned ends 22 of the strap 19 overlap the edges of the body at front and back and sup port the legs securely in closed position.

The top cover or opposite side of the onclosing box or housing of the stove, 23, is hinged to the top edge of the back at 24, and when closed is-securedby the swinging latch hook 25 on thefront, which en 'aoes the projecting loop 26 secured to the front'edge of the said member 28. When the stove is opened for use this lid or cover 23 is swung backwardly on its hinges 24 to substantially horizontal position and is supported in this position, in'which it forms a shelf or tray by the legs 27 rotatably connected to the side edges thereof and held in a sleeve 28 formed by curling over the said side edges of the cover. The outer edge of the cover is turned at substantially right angles thereto to form a flange 29 which houses the legs 27 when they are turned to a position at right angles to their open supporting position, and also overlaps the front of the body to make a comparatively tight closure when the cover is closed down.

.Within the edges of the cover 23 is a shield pivoted thereto by means of the pintles 30 removably connected to the back member of the shield at'its ends by running through the sleeves 4L0 t-hereof and held in the sleeve 31 secured to the inner side of the cover 23 at the rear of its side edges. of the shield are hinged at their back edges to the ends of the rear members 88, as shown. at, 34, 34 where the pintles 30 extend through their sleeves, and extend forwardly to a point beyond'th burners to protect the burners and the articles over them and on the shelf formed by 23. lVhen'the stove frame is folded the side members 32 are first folded back against the back member 33 and the back then turned down in the inside of the cover. .23, so that these parts he fiat against the inner side of said cover.

ous spring rod or wire bent to form an open rid and havi'n itsends turned and held in the sleeves d5 at the back of the burner su porting frame 36; In this manner it is constructed and arranged to be swung to vertical position and down to horizontal position over the burners, and may be removed if do sired b sim l fiercin its ends and with.-

'drawing them from their sleeves.

When it is desired to move the stove, without folding The side members 32 it, this grid may be turned up to vertical p0 sitlon andthe entire stove lifted and carried by using it as a handle.

The construction and arrangement of the burners and tank and the frame for supportmg them are not apart of the present 1mprovements, and are described'and claimed in a copending application by Vlalter C. Lindemann, one of the joint inventors hereofThe frame,however,consists of members arranged" porting legs for said body, burners housed in said body, a cover member hingedly connected with one upper edge of the body and adapted to be swung outwardly to horizontal position to form a supporting shelf or table and inwardly to close the said body por-' tion, leg braces between the leg and body members pivotally connected with one of said members to swing to position between the two members and normally within their edges and capable of being flexed laterally beyond the said members and to spring into an aperture in the other member to form a rigid connection between the said two members.
